Plate movement is thought to be driven by a combination of the motion of the seafloor away from the spreading ridge (due to variations in topography and density of the crust, which result in differences in gravitational forces) and drag, with downward suction, at the subduction zones.

It divides into two strands on unwinding and forms replication fork just like DNA does.And the same unwinded strands can be incorporated into the daughter DNA molecules and thus becomes semiconservative in nature.Source(s): .ating Newest Oldest.

DNA replication is the copying of DNA within the nucleus of a cell so that two full copies are present. This occurs before a cell divides. Two copies of a cellâs DNA need to be present before a cell divides so that each of the resulting two daughter cells will each have one full copy of the cell's DNA.
